Application filed May 31, 1900. Serial No. 18,502. (No model.)

1'0 all whom, it ncay concern.-

Be it known that I, GEORGE E. CHANDLER, of Taunton, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Acetylene-Generators, of which the following is a specification.

This invention has for its object to provide improvements in acetylene-gas generators to prevent premature generation of gas and the escape of gasinto the carbid-inlet and also to effect a better distribution of the carbid on the carbid-support, the novel deflectors employcd serving both in the capacity of carbiddistributers and gas-deflectors.

The accompanying drawing represents a vertical sectional view of an acetylene-generator constructed in accOrdanccwith my invention.

1 is a generating-chamber, closed except for a tubular carbid-inlet 2, extending for a distance into the receptacle, and a gas-outlet 3. 4 is a waste-outlet. The receptacle contains a body of water 9, and it has a support for the cal'cic carbid, the support in this instance being the bottom 11 of the receptacle.

5 is an oil-chamber inclosed by the receptacle l and located in its upper portion and having a contracted or inwardly-tapering lower end, the lower orifice or mouth of said chamber being at a distance above the carbid-support. Within the chamber 5 is a body of oil or other neutral liquid 10, the employment of which for the purpose of preventing premature generation of gas when the carbid is introduced tothe receptacle is a well-known expedient. The oil is supported by the water in receptacle 1, and its lower limitis preferably at the orifice of chamber 5.

Below chamber 5 is a deflector of an inverted-V shape invertical section, its apex being at the month or orifice of said chamber and its spread being greater by a considerable amount than the area of said contracted orifice. The bubbles of gas which rise underneaththe deflectorflaretherefore turned aside and pass around the oil-chamber 5 into the space above the water in receptacle 1, being prevented from entering said oil-chamber even though pursuing a path whichdeparts considerably from the vertical. The deflector (i also serves to divide a charge of carbid descending through the chamber 5, so as to distribute it upon the carbid-support 11 instead of allowing it to fall in a single pile upon said support. The water thus has freer access to the carbid, and the generation of gas ensues more quickly than when the carbid is deposited in a compact mass. An immediate action of the water upon the whole of a charge of carbid is particularly desirable when the charges are introduced auto matically into the generator and are governed by the position of a movable gas-holder. The large volumes generated then cause the receiver to rise past the point at which it effects the introduction of the charge, and thus tend to create a reserve instead of generating the gas only as fast as it is used. The deflector 6 may be of conical, pyramidal, or similar form, or it may be elongated transversely of the generator. Owing to the fact that each recurring charge of carbid descending through the oil-chamber carries some of the oil with it below the orifice of said chamber the water-level will tend after a time to rise more or less into the chamber 5, so that a slight generation of gas may take place before the carbid has left the oil-chamber. To provide against any of this gas or any gas which for other cause may accidentally enter the chamber 5 entering the inlet-tube 2, and thus escaping into the room or space where the generator is placed, I arrange a second deflector 7 within the chamber 5, this deflector being preferably similar in form and function to the deflector 6 and placed with its apex at the lower mouth or orifice of the carbidintroducing tube 2, there being, as in the case of deflector 6, a space for the passage of carbid on either side of said apex between the deflector and the walls of the tube, so that the deflector 7 etfects a predistribution of the charge of carbid, which is continued and carried out by deflector 6.

The deflectors 6 and 7 may be supported in any suitable way, as by providing their bottoms with extensions reaching and secured to the inner walls of the chambers l and 5.

To allow for the escape of anygas which may collect in the upper part of the oil-chamber 5, I provide a branch outlet 8, leading from said chamber to the main gas-outlet 3. While, as above stated, the carbid descendter of fact very little oil manages to escape,

so as to rise through the Water surrounding the chamber 5. This is for the reason that the carbid as soon as it passes out from the lower end of the chamber 5 comes in contact immediately with water, and any oil adhering to the carbid is more apt to leave the carbid as it passes downward through said wa-. ter and rise back again into the chamber 5 than to remain adhering to said carbid as the latter passes below the deflector 6. In normal conditions, therefore, the chamber 5 'retains all of the oil, so that after the carbid once escapes therefrom and passes into the Water the gas generated or nearly all of it rises outside of the chamber 5 and passes upward through water only without having to rise through oil or any appreciable quantity thereof. The gas is therefore practically free from any mixture of oil or' vapor thereof.

The deflector 6 below the lower end of the chamber 5 serves the .purposes above described, while the deflector 7 within the oilchamber prevents the escape of any gas, which may under occasional or some unusual conditions obtain access to thechamber 5,from rising into and escaping through the fillingtube 2.

I claim 1. An acetylene apparatus comprising a generating-receptacle having a support for the carbid and a filling-tube, an inner chamber adapted to confine a body of oil and holdit separate from water in the receptacle around the chamber, said inner chamber surrounds ing the tube and containing a deflector having its apex at the lower mouth-0f said tube, and a deflector in the generating-receptacle below the inner chamber and having its apex at the lower mouth of said chamber.

2. The combination of a generating-receptacle having a tube for the introduction of carbid and a support for the carbid, a chamber adapted to confine a body of oil and hold it separate from water intherecept-acle around the chamber, said chamber being inclosed by said receptacle and containing said tube and a deflector below the lower end of the latter and above the lower end of said chamber, and a shedder or deflector of an inverted-V shape located above the carbid-support with its apex at the lower mouth of said chamber, there being spaces for the passage of carbid between the chamber-walls and the deflector on either side of said apex, the spread of the deflector being considerably greater than the orifice of the chamber, whereby the upward passage of gas into the chamber is prevented. In testimony whereof I have affixed my signature in'presence of two witnesses.
